Purdy’s most popular brushes, the XL™ Series is the most versatile brush series, designed for use with all paints and stains. Highly recommended for both interior and exterior painting projects and with all paints, the stiffness of the brushes makes them ideal for outdoor projects with different temperatures and humidity. A blend of Satin-Edge Nylon (Tynex®) and Orel® Polyester are used and our special tipping and flagging process simulates the ragged ends of natural bristle, so the brush holds more paint and releases it without brush marks. Each XL brush has a unique hand-chiseled formulation for maximum paint lift and smooth “no drag” application. When the job is complete these premium filaments make clean up fast and easy.
